Pandion has already pointed out that this isn't a theory, it's a mode of wishful thinking. More damagingly, however, if you examine it for more than a moment it doesn't even fulfill the role you give it. You say 'many things in nature make no sense without God', but how do god's origins and nature make sense? Where did he/she/it spring from? All you do by invoking god as an 'explanation' is push the problems one step further back. The god hypothesis may look like an explanation, but it is not.
